Not Legit!!!!!! This is just another extortion scam. Don't fall for it!!! Not a real collection agency.
Robocall: "This call is for [the guy we just won't leave alone]. This is Elizabeth xxxxx, Consumer Fraud Investigator...an ITEM has been returned ...is connected to your social security number..."
Gave a case number and a callback number slightly different from caller ID.
It's just amazing how many flavors of extortion there are. Once a name is in the system, they NEVER leave them alone. This has been going on for years. Nothing about this is legal.
